The past is another country but sometimes it's a very recognisable place! Betsy and her new friends cheer boys at the football, and she waits impatiently to be invited to parties, and she develops a massive crush on the new boy in town who has a bad boy air about him.
I liked that Betsy, with all her crushes and her string of beaux, is depicted as one of a spectrum of girls. Some of her friends see all these teen romances as a step towards marriage, with their full hope chests, before they settle down in Deep Valley forever. Others like Tacy simply aren't interested in boys (which I found so interesting, if Tacy had been written today like that I'd assume this was sowing seeds for her to be gay or ace or demi). And Betsy herself, very interested in boys, is after romance and adventure, explicitly thinking to herself that marriage isn't her goal at all and like her sister Julia dreaming of a bigger life after high school.
There's a kind of messiness to the interactions of all these youths - who is 'going with' who, crushes developing, friendships coalescing - especially because few of these threads travel in a linear line. This feels true to life, probably because it was so drawn from Lovelace's own life.
One underlying thread: Betsy's relationship to stories and storytelling. For much of the book she hides it away or forgets about it. Only towards the end does she decide actually, writing is part of her identity.
